类型错误：列表索引必须是整数或切片，而不是字典

Question

我试图从有效负载中返回所有 JSON 数据，但它给出了一个错误TypeError: list indices must be integers or slices, not dict 。

当我print(request.data)时，它只是返回所有 JSON 数据，但是当我执行 for 循环时，它给出了错误

在这里，我尝试了什么

意见.py：

@api_view(['POST'])
def SaveUserResponse(request):
    
    if request.method == 'POST':
     for i in request.data:
        print(request.data)
        auditorid =request.data[i]['AuditorId']
        print('SaveUserResponse auditorid---', auditorid)

        ticketid =request.data[i]['TicketId']
        qid = request.data[i]['QId']
        answer = request.data[i]['Answer']
        sid = request.data[i]['SID']
        print('sid--', sid)


        cursor = connection.cursor()
        cursor.execute('EXEC [dbo].[sp_SaveAuditResponses] @auditorid=%s,@ticketid=%s,@qid=%s,@answer=%s,@sid=%s',
         (auditorid,ticketid,qid,answer, sid,))
        result_st = cursor.fetchall()
        for row in result_st:
            print('sp_SaveAuditResponse', row[0])
        
        return Response(row[0])

    return sid

Answer 1

要遍历列表，请尝试：

for i in my_list:

此外，您设置 JSON/dict 的方式不是有效语法。 您不需要按键枚举列表元素，因为列表会自动编制索引。 键必须始终是字符串。 它应该更像是：

 my_JSON = [{'AuditorId':122, 'Agents': '', ...}, {'AuditorId':122, 'Agents': '', ...}]

比您将能够通过以下方式访问内部词典：

 my_list[i]['AuditorId']
